Using Python 3. I have the following code for the game 2048. the code is pretty much done. The only thing I cannot get to work is how to update the Score after each move. It should work just like when we play 2048, the score updates after each sucessful move. But i cannot do it. Below you will find my code.

import random as rnd import os import sys

class Grid():

def __init__(self, row=4, col=4, initial=2): self.row = row self.col = col self.initial = initial self.score = 0 self.size = row * col

def createGrid(self, row, col): grid = []

for i in range(col): grid.append([0] * row)

return grid def setCell(self, cell, val): row = cell // self.col col = cell % self.row self._grid[row][col] = val
